A nice two-loop next-to-next-to-MHV amplitude in $\mathcal{N}=4$ super-Yang-Mills

Song He, Zhenjie Li, Chi Zhang

We study a scalar component of the 8-point next-to-next-to-maximally-helicity-violating (N${}^2$MHV) amplitude at two-loop level in $\mathcal{N}=4$ super-Yang-Mills theory; it has a l…
